ata: add platform driver for Calxeda AHCI controller
|
||||||
|
|
||||||
|
Calxeda highbank SATA phy has intermittent problems bringing up a link
|
||||||
|
with Gen3 drives. Retrying the phy hard reset can work-around this issue,
|
||||||
|
but each reset also disables spread spectrum support. The reset function
|
||||||
|
also needs to reprogram the phy to enable spread spectrum support.
|
||||||
|
|
||||||
|
Create a new driver based on ahci_platform to support the Calxeda Highbank
|
||||||
|
SATA controller.
